If you're going to make something this short, you should put that much more effort into making it funny, original, and well-animated. Plus, the best "super-short" films are those that actually draw their punchline off the fact that they're short. So people are going to expect things as short as this to be extremely good gags to make up for it. Not saying this isn't funny, but it's really nothing special.
Still, it's a good effort for a first animation, kudos on that.
But please, PLEASE, put a preloader on it next time.
